Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Formation
Wehrlite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

Wehrlite vs Travertine Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Wehrlite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Travertine. Learn more about Wehrlite vs Travertine in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Wehrlite and Travertine, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Travertine include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar.
More about Wehrlite and Travertine
Here you can know more about Wehrlite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Travertine consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Wehrlite is Rough and Banded and that of Travertine is Fibrous. Properties of rock is another aspect for Wehrlite vs Travertine. The hardness of Wehrlite is 5.5-6 and that of Travertine is 3-4. The types of Wehrlite are Not Available whereas types of Travertine are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Travertine is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Travertine is 1.09 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
